Know Least Common Multiple of fractions 90/61, 49/43, 33/29, 42/708 quickly i.e. 48510 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 90/61, 49/43, 33/29, 42/708 is 48510.
LCM(90/61, 49/43, 33/29, 42/708) = 48510
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 90/61,49/43,33/29,42/708
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 90,49,33,42
Least Common Multiple of Numerators i.e. LCM of 90,49,33,42 is 48510.
GCF of Denominators means GCF of 61,43,29,708 as per the given fractions.
GCF of 61,43,29,708 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 90,49,33,42
2 | 90, 49, 33, 42 |
3 | 45, 49, 33, 21 |
7 | 15, 49, 11, 7 |
15, 1, 11, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 15 x 1 x 11 x 7 = 48510
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 90,49,33,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,49,33,42) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(90,49,33,42) x common factors =1 x 126 = 126
LCM(90,49,33,42) = ( 90 × 49 × 33 × 42 ) / 126
LCM(90,49,33,42) = 6112260 / 126
LCM(90,49,33,42) = 48510
Lets's calculate GCF of 61,43,29,708
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 48510/1
Therefore the LCM of Fractions 90/61,49/43,33/29,42/708 is 48510
